SMOKE CLEANER FOR LOCOMOTIVES AND THE LIKE.

Application filed November 14, 1922.

To all whom it may concern:

Be it known that I, JOHN C. YOUNG, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and 5 State of Pennsylvania, have invented certain new and useful Improvements in Smoke Cleaners for Locomotives and the like; and I do hereby declare the following to be a full, clear, and exact description of 1 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a smoke cleaning and spark arresting apparatus for use in connection with locomotives and other boiler furnaces and the like whereby without interfering with the draft of the furnace or fire box and in fact under conditions stimulating the draft, the smoke and other products of combustion may be cleaned and prevented from vitiating the surrounding atmosphere and the danger of flying sparks may be eliminated to minimize the risk of fire and the like, and with these general objects in view, the invention consists in a construction, combination and relation of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a side view of an apparatus embodying the invention applied in the operative position to and associated with a locomotive engine and tender.

Figure 2 is a detail sectional view of the forward or smoke box end of the apparatus,

Figure 3 is a similar view of the rear or smoke cleaning end of the apparatus,

Figure 1 is a detail sectional view of an intermediate portion of the smoke conductor to show the suction or draft inducing fan,

Figure 5 is a detail transverse sectional view on the plane indicated by the line 55 of Figure 2, and

Figure 6 is a detail sectional view on the plane indicated by the line 66 of Figure 2.

The apparatus consists of a steam exhaust pipe 10 having its lower end forked as at 10 and arranged preferably in the smoke box 11 of a locomotive or the equivalent thereof in a stationary boiler furnace, such as the stack, the outlet end of the exhaust pipe being located at or above the top of the smoke box where it passes through a smoke conveyor 12 and communicates with smoke box.

the atmosphere. Extending rearwardly from the smoke box in lieu of the usual smoke stack and preferably provided at an intermediate portion of its length with a draft inducing or reinforcing fan 13 is the smoke conveyor 12. Draft in the smoke box may also be reinforced or accelerated by means of a fan 14 located in the smoke box near its bottom so that an upward current of air may be produced across the front end of the fire tubes 15 of the boiler which is indicated at 16. The steam jet pipe 10 has its lower forked end 10 communicating with steam exhaust boxes 17, one of which is disposed at each side of the locomotive and into which steam may be discharged from the locomotive cylinders or other operating parts or which may be directly charged from the boiler as preferred, no details of supply connections being deemed necessary in the drawings. Extending rearwardly directly from either of the steam exhaust boxes is an auxiliary steam conveyor 18 which communicates with the smoke conveyor 12 preferably in rear of the suction fan 13. The auxiliary steam pipe further serves to induce a rearward draft or current through the smoke conveyor and furnishes an outlet for the steam received by one of the boxes 17 in the event that the forked end 10 of the steam exhaust pipe, which communicates with the selected box is closed by means of a valve 19 which in I locked with the valve in desired position either to cut off the exhaust pipe or to partly or wholly open the same according to the desired stimulation of draft through the It is to be understood that two slide valves 19 are provided, one at each side of the locomotive and one being adapted to cooperat with each of the exhaust boxes 17. As each of the valves 19 is of the same construction, it is thought that the detailed description of one will be suflicient for both.

Openings 20 connect the steam exhaust boxes 17 with the smoke box 11 and the valves 19 may be used to cut off the supply of steam from either or both of the steam exhaust boxes to the smoke box through either or both of the openings 20. However, when additional draft is required a valve 19 or both valves 19 may be moved to bring either or both of the openings 20 into registration with either or both of the openings 20' to admit steam to the smoke box. Arranged in the forward end of the smoke conveyor 12 is an air inlet, the same comprising a flap valve 12 arranged at the forward end of the housing 12 The valve 12 is moved to open position and maintained in such position by the pressure of air against the same when the locomotive is moving at a relatively high rate of speed. If found desirable means under the control of the engineer may be provided with the valve 12 when additional draft is required. Also, if found desirable additional valves 12 may be provided along the length of the smoke conveyor 12, such a valve housing having been illustrated at a point substan tially midway of the conveyor.

At its rear end the smoke conveyor is submerged in a settling tank 22 which in the construction illustrated is seated in and carried by the tender 23 and is provided with an arched or convex cover 24 having a central outlet or vent 25 designed to permit of the escape of vapors or gases which have passed through the liquid contents of the tank, preferably water, and have been relieved of sparks and deleterious properties which are objectionable in the atmosphere because of injury to trees and plants and distress to communities located adjacent to the railway line or to the factory or other establishment using the furnace. The tank 22 is provided with a drain 26, the same being sufficiently large in diameter to permit small cinders to pass therethrough.

It has been deemed unnecessary to show any particular means for actuating or controlling the draft inducing or stimulating fans, it being understood that either steam, electrical or other power may be employed in this connection and that means may be adapted for control by the engineer'to. determine the use and regulation thereof, and which obviously may be of any suitable or conventional form.

What is claimed is An apparatus of the class described for use in connection with boiler furnaces, the same comprising a steam exhaust pipe arranged to extend through the smoke box, a conveyor in communication with the smoke box and extending rearwardly of the furnace for conducting the products of combustion to a point of deposit, a steam exhaust box arranged exterior of said smoke box and having communication with the smoke box, said steam exhaust box having communication with the exhaust pipe, a slide valve arranged to control the passage of steam from the exhaust box to the smoke box and from the exhaust box to the exhaust pipe, and an auxiliary steam conveyor providing communication from said exhaust box to the conveyor for the products of combustion at a point remote from the smoke box to induce a rearward draft through the conveyor for the products of combustion.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN G. YOUNG.
